Q(k) p(k) +-f(k) b 3 b 2 r(k-1) w 1 w 2 A new signaling system for high bit rate wireless LANs is made possible by a novel class of signaling pulses called OWSS pulses, which are generated through a combination of OWDM and spread spectrum concepts.

Mitochondria are the powerhouses of cell. They produce a significant amount energy we need to grow, survive and reproduce. The same system that generates in form ATP also produces Reactive Oxygen Species (ROS). Mitochondrial (mtROS) were considered for many years toxic by-products metabolism, responsible ageing degenerative diseases. Today, know mtROS essential redox messengers required determi...

Intercellular signalling via growth factors plays an important role in controlling cell differentiation and cell movements during the development of multicellular animals. Fibroblast Growth Factor (FGF) signalling induces changes in cellular behaviour allowing cells in the embryo to move, to survive, to divide or to differentiate. Several examples argue that FGF signalling is used in multi-step...

Integrins act at signalling crossroads, and their interactions with other signal transduction pathways are key to the regulation of normal and pathological cell cytoarchitecture and behaviour. Here, we describe a signalling cascade that acts during the formation of the defining segmental features of the vertebrate body - the somites - in which β1-integrin activity regulates epithelialisation by...


 Purpose: To determine the antitumor effect of demethoxycurcumin on lung cancer cells, as well its PI3K/AKT/m-TOR signalling, cellular apoptosis, cell migration and invasion.
 Methods: Cell viability was determined using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay, while AO/EB annexin V/PI staining assays were used for apoptosis analysis in demethoxycurc...
